all whom it may concern:

Be it known that 1, CHARLES STIRIZ, a citizen of the United States, anda resident of the cityof New York, borough of Manhattan, in the countyand State of-New York, have invented a new and ImprovedInternal-Combustion Engine, of which the following is afull, clear, andexact description.

My invention relates to internal combustion engines, my more particularpurpose being to provide such devices with an improved water jacket inwhich the water is caused to circulate by the conjoint action ofcentrifugal force and difference in density between hot and cold water.

My invention also contemplates an engine made up of a plurality of unitsso arranged that when an explosion takes. place in one'unit, the gasesof combustion are con ducted to another unit, and there mixed withsteam,this mixture then expanding and doing work within the second unit.

My invention further eomprehends y'arious details of constructionwhereby the efiicienoy of the engine is greatly improved.

ing a general annular form and secured in position by aid of screw bolts16.

A hydro-carbon supply pipe is shown at 17 and is provided with a nozzle17 Mounted rigidly. upon 'thisnozzle is a ring 18 and engaging thelatter is a worm 19. This worm is connected to a. hand wheel 20 andisjournaled within a bracket 21. The nozzle 17 extends through the disk12. Secured upon the disk 12 is a tube 22 provided Withan air hole 23.The nozzle 17 extends into this tube 22 and is coaxial therewith. Avalve having generally a cylindrical-form is provided with holes 24 andis revolubly mounted within the tube 22. connected With the tube 22 andis disposed adjacent to the valve 25. This valve is adapted to turn stepby'step and in so doing brings the holes 24- successively into registrywith the tube 26. The valve 25 is provided with a stem 27 and mountedfirmly upon this stem is a so-called Geneva cross 29. A cam wheel isdisposed adjacent to this cross and is provided with lugs 28 arranged asshown in Fig. 1, and adapted to successively turn the cross 29 and thusactuate the valve 25 step by step. The valve 25 and parts immediatelyassociated therewith together constitute a carbureter.

The pipe 26, at its outer end, is connected with a wall 31 having theshape indicated in Fig. 1. This wall is integral with a ring 32 which issupported upon spokes 32 and is provided with an inclined portion 33,the latter being integral with the wall 31, these two parts togetherforming an abutment which receives the force of the exploding gases.This abutment is provided with my newly invented packing 34. A revolublecasing 35 is provided with an inner wall 35 and an outer wall 35' andWith a passage 36 disposed between these walls. A pipe 37 communicateswith this'passage and also communicates with an annular passage 38located within a hub 38 with which the casing 35 is provided. Anotherpipe 39 communicates with the passage 36 and with an annular passage 40,the latter being located within thehub 38. The revoluble casing 85 ispartly supported upon a number. of rolling bodies 41 arranged in acircle around the disks .7, 12, and constituting a ball bearing.The-casing 35 is providedwith two compartments 42, as will be understood,from Fig. 1. #In each of these compartments 15.11

A pipe 26 isa contact 44.

spark plug 43, and adjacent to the latter is This contact is connectedwith a binding post 41 and is adapted to be closed and opened as thecasing turns. Two gates 45 are carried by the casing and located withinthe compartments 42. Each gate 4-5 is mounted upon a-rockingshaft 46,and connected rigidly with the latter is an arm 47 carrying a roller 48.This roller runs upon the cam frame 14, the latter being provided with acam 49 extending outwardly, as will be understood from Figs. 1 and 2.

A pipe 50 extends through the ring 32 and across the machine, beinconnected with an abutment 51 carried a casing 51. This abutmentispractically an extension of a ring 52. The revoluble casing 51 isprovided with two gates 53 disposed diametrically opposite each otherand located in compartments 54. Each of these gates is free to swing andis provided with an arm 55 carrying a roller 56 which runs upon the camframe 15. This frame is provided with a cam 15 which periodically guidesthe rollers 56 outwardly and in so doing turns the gate 53.

A cam wheel 57 turns with the casing 51- and-engages a cross 58 similarto the cross 29 and turns the latter step by step. Connected with thecross 58 is a rotary valve 59 which is mounted within a valye casing 60and connected with a steam pipe 61."v This steam pipe taps into thetubular hub ll and, as the casing 51 turns, is periodically brought intoengagement with each hole 9.

. The pipe (ii-terminates in a nozzle 62 which extends into thecompartment '54. Apipe 63 is connected with the compartment 54: andserves to d scharge the gases of combustion as they finally emerge fromthe machine'. A power wheel 64 is connected rigidly with the tubularshaft 4, and is turned thereby for the purpose of transmitting throughthe opening 23. the explosive mixture is forced through the pipe 26' andinto the explosion chamber. Each time the casing 35 makes a turn. eachdoor 45 is opened and closed by the action. of its roller 48 upon theadjacent cam frame 14.- and cam 49. The

gate 45 is always closed, as indicated in Fig.

1, when the explosion takes place; Each gate 45, upon a proaehing thelnclined'portion 38 of the ring 32, rides outwardly upon this portionand, upon traveling around a little farther, is free to close which itdoes under the guidance of the cam roller associated with it.

The gases of combustion pass'through the pipe 50 across the machine andare admitted intothe compartment 54, so as to heatup their surroundingsand exert a constant pressure. Here they unite with steam from thenozzle 62, this steam being discharged periodically and at the rightmoment to come into con tact with the exhaust gases just mentioned.

The mixture of the exhaust gases and the steam causes rapid'expansion,and this assists in driving the revoluble casing 51. When thegasesfinally escape through the pipe 63 they have completed their work.

Water being admitted through the pipe'5 has free circulation through thepipe 37 out into the compartment 36 of the casing 35 and back throughthe. pipe 39 to the tube 4 from whence it makes its escape. As thewater, while in the compartment 36, is heated by the explosions,thediiference in the specific gravity of the water thus heated and thecold water as it enters is suflicient, in connection with the action ofcentrifu al force, to cause the water to circulate freely; that is tosay, the mere heating of the wa ter, by slightly lessening its specificgravity, causes the machine in acting under centrifugal force to actwith greater intensity upon the cold water when it enters than upon -thehot water already in the machine,.so that the net result is a tendenc'upon the .part of the machine, to induct the cold water and throw it tothe outside, the hot water in the meanwhile constantlymaking its escape.

This tends to keep the coldest portions of the water out near the edgeof the revoluble casing where the greatest heat would otherwise bedeveloped. It also renders the circulation of the Water completelyautomatic in the sense that no pump or similar device is necessary inorder to effect a good circulation. Each time the cam wheel 30 causesthe cross 29 to turn a. quarter of a revolution, the carbureter isactuated accordingly, being either opened or closed, as the case may be,so that the carbureter is closed whenever the engine is in condition foran explosion to take place. Similarly, whenever the cam wheel 57 causesthe cross 58 to turn the valve 59, this valve always stops 'in suchposition that an explosion within the explosion chamber 54 cannot forceanygases of combustion through the pipe 61.

I do not limit myself to the particular construction here shown anddescribed, as variations may be made therein without departing from thespirit of my invention, the scope of which is commensurate with myclaims. Neither do limit myself in every instance to the use ofexplosions, as in some.

relations various other modes of propulsion may be employed, all comingwithin the I claim as new and desire to secure by Letters Patent is2-- 1.
